Osg 484-1875 Square End Mill 3/16 in 4 Flute Carbide

Product Description

The OSG 484-1875 is a solid carbide square end mill designed for precision milling operations in ferrous and non-ferrous materials. With a 3/16 inch cutting diameter and four spiral flutes ground from micrograin carbide, this tool delivers clean square shoulders and flat-bottom pockets. The 30-degree helix angle promotes efficient chip evacuation and reduces cutting forces. At 3 inches overall length with a 1-1/8 inch length of cut, this is an extra-long configuration suited to applications that require extended reach into deeper features. Installation and operation are performed by machinists and CNC setup technicians.

This end mill fits standard 3/16 inch collets or tool holders in vertical machining centers, CNC mills, and manual knee mills. The uncoated micrograin carbide construction makes it suitable for general-purpose slotting, profiling, and plunging cuts where center-cutting capability is required. The extra-long overall length makes it appropriate for mold work, die cavities, or any application where standard-length tooling cannot reach the workpiece feature. No specific compatible machine models are listed by the supplier.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance in precision milling
• Four spiral flutes with 30-degree helix angle for efficient chip removal
• Center-cutting design allows direct plunge entry into workpiece material
• Extra-long 3 inch overall length with 1-1/8 inch length of cut for extended reach applications
• Right-hand cut, right-hand flute configuration — standard orientation for CNC and manual mills
• Uncoated finish suitable for general-purpose applications across a range of materials

Compatibility

Designed for use in any machine tool or CNC machining center equipped with a 3/16 inch collet, end mill holder, or equivalent tool-holding system. Part of the OSG Series 484 extra-long square end mill family.

Installation Notes

Installation should be performed by a qualified machinist or CNC technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Insert the shank fully into the collet or holder to the recommended engagement depth and torque the retention mechanism per the tool-holder manufacturer specifications. Inspect the cutting edges for chips or damage before each use.
